AbstractThe European pompilid Agenioideus cinctellus (Spinola, 1808) is recorded for the first time from the New World based on material from Ontario. Another recent Nearctic immigrant, Auplopus carbonarius (Scopoli, 1763), is recorded for the first time from Canada, which extends its known range into southern Ontario. The incidence of new introductions and the possible impact on the community of cavity-nesting aculeate wasps is discussed.

AbstractSolitary cavity-nesting bees, especially trap-nesting Megachilidae, have great potential as commercial pollinators. A few species have been developed for crop pollination, but the diversity, abundance, and potential pollination contributions of native cavity-nesting bees within agricultural systems have seldom been assessed. Our objectives were to compare the diversity and fecundity of cavity-nesting bees in Nova Scotia in natural ecosystems with those in apple orchards under three levels of management, using trap nests, and to determine whether any native bees show promise for development as pollinators. Our results show that species richness and numbers of bees reared from trap nests in commercially managed orchards, abandoned orchards, and natural habitats were similar, and species’ compositional patterns were not unique to specific habitats. Trap nests can be used to increase and maintain cavity-nesting bee populations within Nova Scotia apple orchards. Osmia tersula Cockerell (Megachilidae), which accounted for almost 45% of all bees captured and was the most abundant species nesting in all habitats evaluated, should be assessed for potential as a commercial pollinator of spring-flowering crops. The influence of natural cavities on bee species richness in trap-nesting surveys is also discussed.

Phyllonorycter Blancardella

AbstractThe braconid Pholetesor (= Apanteles) ornigis (Weed) was the major parasite of the spotted tentiform leafminer, Phyllonorycter blancardella (Fabr.), at 21 sites, in 9 counties in southern Ontario. The eulophids Sympiesis sericeicornis (Nees) (12 sites, 6 counties), S. dolichogaster Ashmead (9 sites, 5 counties), S. marylandensis Girault (8 sites, 6 counties) and Pnigalio maculipes (Crawford) (6 sites, 5 counties) were the major chalcidoids recovered. Other species recovered were 10 eulophids, 2 pteromalids, and 2 ichneumonids. The major hyperparasite of P. ornigis was S. sericeicornis, but S. dolichogaster, Habrocytus sp., Catolaccus sp., Gelis sp., and Hypopteromalus sp. were also recovered.

Pine Species

All pine species in Florida are susceptible to red heart disease. The disease can decrease timber value and weaken trees, making them threats to people and property. In forests, however, the same disease can be beneficial to cavity-nesting animals like red-cockaded woodpeckers. This 3-page fact sheet written by Yin-Tse Huang, Jeffrey Eickwort, and Jiri Hulcr and published by the UF/IFAS School of Forest Resources and Conservation describes the disease and provides some tips to manage it in areas where it could cause problems for people.http://edis.ifas.ufl.edu/fr425
